        A fresh install causes the same error for me, once stateless IPv6 is setup. I can't find a stable working system whatever I do, other than back to 2.4.

        Because I'm using an ESXi testbed, it's easy to spin up new installs.

        I do think there is something fundamental here, given the reports from wide ranging setups.

          the error is generated from device-bsd44.c, a patch it's inside the port of radvd for freebsd
          tracking back there was similar problem. related Bug #2878 https://redmine.pfsense.org/issues/2878 from 2013

          /* XXX: See pfSense ticket #2878 */
+	setsockopt(sock, IPPROTO_IPV6, IPV6_LEAVE_GROUP, &mreq, sizeof(mreq));
+
+	if (setsockopt(sock, IPPROTO_IPV6, IPV6_JOIN_GROUP,
+			&mreq, sizeof(mreq)) < 0) {
+		flog(LOG_ERR, "can't join ipv6-allrouters on %s", iface->props.name);
+		return (-1);
+ }

          maybe it's time for a new ticket

            idk if we open a ticket devs might just ignore it, first we should get devs on the forums to tell us if we need to open a bug.

              @strangegopher - they're aware of it, one of the devs referred to the ticket in a thread with an issue I'm having.

                        i put here a workaround that seems to work for me

                        [2.5.0-DEVELOPMENT][root@pfSense.localdomain]/root: crontab -l
@hourly killall radvd && sleep 5 && /usr/local/sbin/radvd -p /var/run/radvd.pid -C /var/etc/radvd.conf -m syslog

                          On the recent snapshot (2.5.0.a.20190728.0536) I now also get the following repeated in the routing system log:

                            Yup same here, 2.5.0 is getting worse by every snapshot 😁
                            Ah well probably Ill go back to 2.4.4...

                              Looks like it is failing within this code in device-linux.c in radvd:

                              int check_ip6_forwarding(void)
{
	int value;
	FILE *fp = NULL;

	fp = fopen(PROC_SYS_IP6_FORWARDING, "r");
.
.
.

                              Which I think is checking for /proc/sys./... but there is no /proc/sys/... directory. There is also alternative code called in device-bsd44.c. So I'm wondering if radvd in 2.5.0 is being built for the wrong platform, or it's expecting a file that is now removed. But I admit this is a wild guess.

                                Netgate can't possibly ship 2.5.0 with this bug that essentially disables ipv6 support in pfsense. Still no dev replies or acknowledgment of Bug #9577. Hope people that are paying for netgate products or support ask for this to be fixed.

                                  Actually it is working for me, it's only a message log spamming out, they have time to correct it before the official release

                                    It's "working" here too with a radvd restart every 6 hours. I do a radvd service restart via Cron instead of a kill, which seemed cleaner but my approach causes IPv6 sessions to be dropped when the prefix is unadvertised briefly.

                                    Looking at the source code, that spam logging should not even be executing on a freebsd platform. So maybe it's a hint of what's broken.

                                      After 6 days my IPv6 died as well.
                                      Static assigned IPv6 works just fine, slaac and RA doesn`t. Client does not get IPv6 address at all.

                                            @kiokoman said in ipv6 broken: radvd: can't join ipv6-allrouters on <interface>:

                                            i put here a workaround that seems to work for me

                                            [2.5.0-DEVELOPMENT][root@pfSense.localdomain]/root: crontab -l
@hourly killall radvd && sleep 5 && /usr/local/sbin/radvd -p /var/run/radvd.pid -C /var/etc/radvd.conf -m syslog

                                            What is this principle?
